Generation And Characterization Of In Vitro Transcribed Mrna, Cristina Poveda, Yi-Lin Chen, Ulrich Strych

Faculty, Staff and Students Publications

Here we describe the in vitro preparation of mRNA from DNA templates, including setting up the transcription reaction, mRNA capping, and mRNA labeling. We then describe methods used for mRNA characterization, including UV and fluorescence spectrophotometry, as well as gel electrophoresis. Moreover, characterization of the in vitro transcribed RNA using the Bioanalyzer instrument is described, allowing a higher resolution analysis of the target molecules. For the in vitro testing of the mRNA molecules, we include protocols for the transfection of various primary cell cultures and the confirmation of translation by intracellular staining and western blotting.

Faculty, Staff and Students Publications

Exposure and cognitive-based therapies are both effective for PTSD, but knowledge of which intervention is best for which patient is lacking. This lack of knowledge is particularly noticeable for group treatments, as no study has examined whether responses to different group therapies are associated with different pretreatment characteristics. Here, we explored whether pretreatment levels of three types of psychological characteristics-PTSD symptom clusters, posttraumatic cognitions, and emotion regulation difficulties-were associated with symptom reduction during group-delivered cognitive versus exposure-based PTSD treatment. Participants were Veterans with PTSD drawn from two previous clinical trials: one of group CPT (GCPT;

Faculty, Staff and Students Publications

BACKGROUND: Cardiovascular disease commonly affects advanced liver disease patients. They undergo cardiac interventions to improve cardiac outcomes. Cirrhosis increases complication risk, including bleeding, renal and respiratory failure, and further decompensation, including death, posing a clinical dilemma to proceduralists. Predicting outcomes is crucial in managing patients with cirrhosis. Our aim was to systematically review clinical parameters to assess the mortality and complication risk in patients with cirrhosis undergoing cardiac interventions.

METHODS: We searched cirrhosis and cardiovascular intervention terminology in PubMed and Excerpta Medica Database (EMBASE) from inception to January 8, 2023. We included studies reporting clinical scores (e.g. Model for End-stage …

A Comprehensive Meta-Analysis Of Tissue Resident Memory T Cells And Their Roles In Shaping Immune Microenvironment And Patient Prognosis In Non-Small Cell Lung Cancer, Aidan Shen, Aliesha Garrett, Cheng-Chi Chao, Dongliang Liu, Chao Cheng, Zhaohui Wang, Chen Qian, Yangzhi Zhu, Junhua Mai, Chongming Jiang

Faculty, Staff and Students Publications

Tissue-resident memory T cells (TRM) are a specialized subset of long-lived memory T cells that reside in peripheral tissues. However, the impact of TRM-related immunosurveillance on the tumor-immune microenvironment (TIME) and tumor progression across various non-small-cell lung cancer (NSCLC) patient populations is yet to be elucidated. Our comprehensive analysis of multiple independent single-cell and bulk RNA-seq datasets of patient NSCLC samples generated reliable, unique TRM signatures, through which we inferred the abundance of TRM in NSCLC. We discovered that TRM abundance is consistently positively correlated with CD4+ T helper 1 cells, M1 macrophages, and resting dendritic cells in the TIME. …

Functional roles of SIGLEC15 in hepatocellular carcinoma (HCC) were not clear, which was recently found to be an immune inhibitor with similar structure of inhibitory B7 family members. SIGLEC15 expression in HCC was explored in public databases and further examined by PCR analysis. SIGLEC15 and PD-L1 expression patterns were examined in HCC samples through immunohistochemistry. SIGLEC15 expression was knocked-down or over-expressed in HCC cell lines, and CCK8 tests were used to examine cell proliferative ability in vitro. Influences of SIGLEC15 expression on tumor growth were examined in immune deficient and immunocompetent mice respectively. Co-culture system of HCC cell lines and …

Reproductive Factors And Their Association With Physical And Comprehensive Frailty In Middle-Aged And Older Women: A Large-Scale Population-Based Study, Wenting Hao, Qi Wang, Ruihong Yu, Shiva Raj Mishra, Salim S Virani, Nipun Shrestha, Chunying Fu, Dongshan Zhu

Faculty, Staff and Students Publications

Study question: Are women's reproductive factors associated with physical frailty and comprehensive frailty in middle-age and later life?

Summary answer: Early menarche at < 13 years, age at menopause < 45 years, surgical menopause, experiencing miscarriage and a shorter reproductive period of < 35 years were associated with increased odds of frailty, while having two or three children was related to decreased likelihood of frailty.

What is known already: Evidence has shown that women are frailer than men in all age groups and across different populations, although women have longer lifespans. Female-specific reproductive factors may be related to risk of frailty in women.

Study design size duration: A population-based cross-sectional study involved 189 898 women from the UK Biobank.

Participants/materials setting methods: Frailty phenotype and frailty index were used to assess physical frailty and comprehensive frailty (assessed using 38 health indicators for …

Development Of A Mini Pig Model Of Peanut Allergy, Akhilesh Kumar Shakya, Brittany Backus, Lazar D Nesovic, Malini Mallick, Olivia Banister, Carla M Davis, Sara Anvari, Harvinder Singh Gill

Faculty, Staff and Students Publications

INTRODUCTION: The prevalence of peanut allergies is increasing, emphasizing the need for an animal model to enhance our understanding of peanut allergy pathogenesis and to advance diagnostic tools and therapeutic interventions. While mice are frequently used as model organisms, their allergic responses do not fully mirror those observed in humans, warranting the exploration of a higher animal model. The porcine gastrointestinal system closely resembles that of humans, and exhibits allergy symptoms akin to human responses, making pigs a promising model for peanut allergy research.

METHODS: In this study we compared two allergen sensitization protocols involving either topical allergen application after …

Functional Genomics And Small Molecules In Mitochondrial Neurodevelopmental Disorders, Daniel G Calame, Lisa T Emrick

Faculty, Staff and Students Publications

Mitochondria are critical for brain development and homeostasis. Therefore, pathogenic variation in the mitochondrial or nuclear genome which disrupts mitochondrial function frequently results in developmental disorders and neurodegeneration at the organismal level. Large-scale application of genome-wide technologies to individuals with mitochondrial diseases has dramatically accelerated identification of mitochondrial disease-gene associations in humans. Multi-omic and high-throughput studies involving transcriptomics, proteomics, metabolomics, and saturation genome editing are providing deeper insights into the functional consequence of mitochondrial genomic variation. Integration of deep phenotypic and genomic data through allelic series continues to uncover novel mitochondrial functions and permit mitochondrial gene function dissection on an …

Understanding The Role Of Ampa Receptors In Autism: Insights From Circuit And Synapse Dysfunction, Andres Jimenez-Gomez, Megan X Nguyen, Jason S Gill

Faculty, Staff and Students Publications

Autism spectrum disorders represent a diverse etiological spectrum that converge on a syndrome characterized by discrepant deficits in developmental domains often highlighted by concerns in socialization, sensory integration, and autonomic functioning. Importantly, the incidence and prevalence of autism spectrum disorders have seen sharp increases since the syndrome was first described in the 1940s. The wide etiological spectrum and rising number of individuals being diagnosed with the condition lend urgency to capturing a more nuanced understanding of the pathogenic mechanisms underlying the autism spectrum disorders. The current review seeks to understand how the disruption of AMPA receptor (AMPAr)-mediated neurotransmission in the …

Schizophrenia is a complex psychiatric disorder with genetic and phenotypic heterogeneity. Accumulating rare and genome-wide association study (GWAS) common risk variant information has yet to yield robust mechanistic insight. Leveraging large-scale gene deletion mouse phenomic data thus has potential to functionally interrogate and prioritize human disease genes. To this end, we applied a cross-species network-based approach to parse an extensive mouse gene set (188 genes) associated with disrupted prepulse inhibition (PPI), a Schizophrenia endophenotype. Integrating PPI genes with high-resolution mouse and human brain transcriptomic data, we identified functional and disease coherent co-expression modules through hierarchical clustering and weighted gene co-expression …

The Texas Heart Institute Journal

BACKGROUND: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is quickly becoming a routine and effective means by which to treat degenerated bioprosthetic valves. A known complication of ViV-TAVI is patient-prosthesis mismatch, which substantially affects survival. Bioprosthetic valve fracture is a method by which to reduce the risk of patient-prosthesis mismatch and post-ViV-TAVI transvalvular gradients. This study sought to determine the safety and efficacy of post-ViV-TAVI bioprosthetic valve fracture.

METHODS: Patients with a history of surgical aortic valve replacement undergoing ViV-TAVI bioprosthetic valve fracture (N = 25) at the corresponding institution from 2015 to 2022 were cataloged for a retrospective analysis. …

Rragd-Associated Autosomal Dominant Kidney Hypomagnesemia With Cardiomyopathy: A Review On The Clinical Manifestations And Therapeutic Options, Francesco Trepiccione, Irene Sambri, Barbara Ruggiero, Francesco Emma, Andrea Ballabio, Giulia Florio, Ines Vanderheyden, Anna Iervolino, François Jouret

Duncan NRI Faculty and Staff Publications

Background: A hereditary condition primarily affecting the kidneys and heart has newly been identified: the RRAGD-associated autosomal dominant kidney hypomagnesemia with cardiomyopathy (ADKH-RRAGD). This disorder is characterized by renal loss of magnesium and potassium, coupled with varying degrees of cardiac dysfunction. These range from arrhythmias to severe dilated cardiomyopathy, which may require heart transplantation. Mutations associated with RRAGD significantly disrupt the non-canonical branch of the mechanistic target of rapamycin complex 1 pathway. This disruption hinders the nuclear translocation and transcriptional activity of the transcription factor EB a crucial regulator of lysosomal and autophagic function.

Summary: All identified RRAGD variants compromise …

Klebsiella Pneumoniae Carbapenemase Variant 44 Acquires Ceftazidime-Avibactam Resistance By Altering The Conformation Of Active-Site Loops, Zhizeng Sun, Hanfeng Lin, Liya Hu, Neetu Neetu, Banumathi Sankaran, Jin Wang, B V Venkataram Prasad, Timothy Palzkill

Faculty, Staff and Students Publications

Klebsiella pneumoniae carbapenemase 2 (KPC-2) is an important source of drug resistance as it can hydrolyze and inactivate virtually all β-lactam antibiotics. KPC-2 is potently inhibited by avibactam via formation of a reversible carbamyl linkage of the inhibitor with the catalytic serine of the enzyme. However, the use of avibactam in combination with ceftazidime (CAZ-AVI) has led to the emergence of CAZ-AVI-resistant variants of KPC-2 in clinical settings. One such variant, KPC-44, bears a 15 amino acid duplication in one of the active-site loops (270-loop). Here, we show that the KPC-44 variant exhibits higher catalytic efficiency in hydrolyzing ceftazidime, lower …

Improved Sequence Mapping Using A Complete Reference Genome And Lift-Over, Nae-Chyun Chen, Luis F Paulin, Fritz J Sedlazeck, Sergey Koren, Adam M Phillippy, Ben Langmead

Faculty, Staff and Students Publications

Complete, telomere-to-telomere genome assemblies promise improved analyses and the discovery of new variants, but many essential genomic resources remain associated with older reference genomes. Thus, there is a need to translate genomic features and read alignments between references. Here we describe a new method called levioSAM2 that accounts for reference changes and performs fast and accurate lift-over between assemblies using a whole-genome map. In addition to enabling the use of multiple references, we demonstrate that aligning reads to a high-quality reference (e.g. T2T-CHM13) and lifting to an older reference (e.g. GRCh38) actually improves the accuracy of the resulting variant calls …

PURPOSE: Improving the treatment of psoriasis is a serious challenge today. Psoriasis is an immune-mediated skin condition affecting 125 million people worldwide. It is commonly treated with cyclosporine-A (CsA) and dithranol (DTH). CsA suppresses the activation of T-cells, immune cells involved in forming psoriatic lesions. Meanwhile, DTH is a potent anti-inflammatory and anti-proliferative drug that effectively reduces the severity of psoriasis symptoms such as redness, scaling, and skin thickness. CsA and DTH belong to BCS class II with limited oral bioavailability. We aim to develop a drug delivery system for topical co-delivery of CsA and DTH, exploring its therapeutic potential. …

Faculty, Staff and Students Publications

BACKGROUND & AIMS: The protection provided by rotavirus (RV) vaccines is highly heterogeneous among individuals. We hypothesized that microbiota composition might influence RV vaccine efficacy.

METHODS: First, we examined the potential of segmented filamentous bacteria (SFB) colonization to influence RV vaccine efficacy in mice. Next, we probed the influence of human microbiomes on RV vaccination via administering mice fecal microbial transplants (FMTs) from children with robust or minimal RV vaccine responsiveness. Post-FMT, mice were subjected to RV vaccination followed by RV challenge.

RESULTS: SFB colonization induced a phenotype that was reminiscent of RV vaccine failure (ie, failure to generate RV …
